fe3o4 magnetic nanoparticles/ graphene oxide nanosheets/carbon cloth as an electrochemical sensing platform

To eliminate the (rr1346), which is considered as a waste in wastewater from dye industries, the electrochemical advanced oxidation process is used in this study. graphene oxide coated carbon cloth (go/cc) and fe3o4 /go coated carbon cloth (fe3o4/go/cc) electrodes are fabricated by synthesis of go and fe3o4 nanoparticles. characteristic properties such as surface morphology as the main reason for utilizing fe2o3/go/cc as electrodes have been investigated and determined by various instrumental analyses including atomic force microscopy (afm), field emission scanning electron microscopy (fesem), cyclic voltammetry (cv), and cathodic polarization. in addition, for investigating the process yield by the mentioned electrodes, uv-vis spectrophotometric analysis has been conducted to determine dye concentration in the sample wastewater. after comparing the removal efficiency of fabricated electrodes at the same time intervals and determining the concentration of rr1346 dye in samples after oxidation process at different time intervals, results indicated better removal efficiency of fe3o4/go/cc fabricated electrode than the other two electrodes, in which this conclusion was proved by afm, fesem, and uv-vis results
